Which of the Following are the Least Mobile Protists

Question

Which of the following are the least mobile protists?
A) heterokonts
B) diatoms
C) euglenoids
D) apicomplexans

Accepted Answer

Apicomplexans are the least mobile protists among the options given. They are mostly parasitic and have a specialized structure called an apical complex that helps them invade host cells, but this does not facilitate movement in the same way as the flagella or pseudopods found in other protists.
